RN Exception: Mobx Can't find variable: Symbol

异常

Can't find variable: Symbol

解决方法

1. 在你的package.json中的dependencies添加jsc-android

"dependencies": {
    "jsc-android": "^236355.1.1"
  },

或者直接使用命令npm install --save jsc-android

2. 修改android/build.gradle文件

allprojects {
  repositories {
    jcenter()
    maven {
      // All of React Native (JS, Obj-C sources, Android binaries) is installed from npm
      url "$rootDir/../node_modules/react-native/android"
    }
    maven {
      // Local Maven repo containing AARs with JSC library built for Android
      url "$rootDir/../node_modules/jsc-android/dist"
    }
  }
}

3. 修改android/app/build.gradle文件

+configurations.all {
+    resolutionStrategy {
+        force 'org.webkit:android-jsc:r236355'
+    }
+}
 
dependencies {
    implementation fileTree(dir: "libs", include: ["*.jar"])
}

jsc-android
